Summary

Problems

Wind Slabs

30-50cm of wind affected snow preserves two touchy surface hoar layers. These layers sit on a crust on solar aspects. Slab avalanches in wind affected terrain and sluffing where this snow is protected can be expected today.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Likely

Expected Size

1 - 3

Storm Slabs

Thin wind slabs formed by SW winds are now buried by up to 45cm and will be harder to identify. Skiers have triggered windslabs in steep alpine terrain. These windslabs can be high consequence if over a cliff or terrain trap.

Aspects: North, North East, East, South East, South, South West.

Elevations: Alpine, Treeline.

Likelihood
